Transport is responsible for a quarter of the greenhouse gas emissions in Europe, so the European Commission has developed various strategies and directives designed to reduce dependence on oil, and the transport gas emissions ...

Drainage and management of pristine peatlands increase greenhouse gas emissions into the atmosphere. A recent study, based on a new, wide data set collected from northern peatlands indicates that particularly those peatlands ...

The conversion of arctic and boreal wetlands into agricultural land results in an additional cumulative radiative forcing of about 0,1 MilliJoule (mJ) per square meter for the next 100 years. The conversion of temperate wetlands ...

President Barack Obama ordered the federal government on Thursday to cut its greenhouse gas emissions by nearly half over the next decade, driving his climate change agenda forward despite percolating challenges from Republican-led ...

Agricultural greenhouse gases (GHG) make up 8.1% of total U.S. GHG emissions. The dairy cattle farming industry is being challenged to reduce greenhouse gas emissions while maintaining or increasing profitability. In a study ...

Greenhouse gas

Greenhouse gases are gases in an atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. Common greenhouse gases in the Earth's atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In our solar system, the atmospheres of Venus, Mars and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would be on average about 33°C (59°F) colder than at present.

Human activities since the start of the industrial era around 1750 have increased the levels of greenhouse gases in the atmosphere. The 2007 assessment report compiled by the IPCC observed that "changes in atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balance of the climate system", and concluded that "increases in anthropogenic greenhouse gas concentrations is very likely to have caused most of the increases in global average temperatures since the mid-20th century".
